M23 does a 10° axis difference matter for high prescriptions?
I recently received a prescription for high myopia (-8.,50D, -0.75 cyl previouse one was just -6.75 from 5 years ago ). I felt like the first ophthalmologist was in a rush, so I decided to get a second opinion. Both doctors prescribed the same sphere and cylinder, but the axis for my left eye differed: the first one was 170° and the second was 160°.
I chose to go with the 160° prescription, and I’ve been wearing these glasses for two days now. I’m feeling eye strain on left eye and a sensation that my right eye is more dominand, which is making me doubt my decision.
Is a 10° difference in axis significant for such a high prescription? Should I be able to notice a clear difference in visual clarity between these two axes? Also, could wearing glasses with an incorrect axis cause any permanent eye damage? Any advice would be greatly appreciated.
